Qualcomm has a wirelessly charging RC car that looks just like a miniature version of Di Grassi's open-wheel racecar. After racing around for a little bit, the two of them even mange to do some concentric donuts. Naturally, the real Formula E looks a whole lot cooler creating a smokescreen from its spinning rear wheels, but we give Qualcomm full points for the effort.
Qualcomm calls its wireless charging tech Halo and is working to bring the system to the streets. To show things off, the BMW i8 safety car that Formula E employs can already charge without cords, and some racers in the series might be able to next season, too. The solution isn't expected to be production-ready for at least another three years. Qualcomm also has deals in place with Renault and Daimler to bring this and other innovations into the real world... eventually.
